' Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed November 8, 1907. Serial No. 401,260.

To all whom it may concern: I

Be it known that ROBERT Dawson, de ceased, late of Saxonville, in the county of Middlesex and State of invent certain new and useful Improvements in Machines for Coiling and Packing tion.

This invention relates to an apparatus for putting wool or other fibrous materials into receptacles wherein it may. be dyed.

In an application for patent filed by said Robert Dawson, January 10, 1906, Serial N 0. 295,422, is described a' method of dyeing fibers, and a can having perforated inner and outer cylindrical walls between which are contained the fibers to be dyed, which are loosely engaged together in a sliver or top arranged in a circular series of coils in the space between the walls.

It is the object of the present invention to provide a machine by which cans of this character may be filled with fiber and compressed to exactly the right degree, so that the fibers will be sufiiciently loose to oppose practically no obstruction to the flow of dye liquor, and at the sametime to have as great a quantity of fiber as can beefiiciently acted upon at .one time.

The present machine is designed to fee and compress a sliver composed of the fibers with the least possible expenditure of time. In a previous application filed May 5, 1906, Serial No. 315,453, a machine for this purpose is described, in which the cans after being filled with the material, are moved under a pressing device, and'after the material has been. sufficiently compressed are again brought under the'feeding devices to fill the space left by the first compression. L

The present invention is designed to perform a similar result in lesstime, and -to that end the feeding devices and packer or presser are mounted so that each may be placed over a can' in turn, and displaced without requiring any movement of the can itself. I A Of the accompanying drawings,-Figure 1 represents a side elevation of a machine embodying the present invention, showing the parts in position'tofeed a sliver of the fibrous material. Fig. 2 represents an elevation of the upper part of the machine. showing the packing device in operative Massachusetts, did

Fiber, of which the following'is a specificaposition. Fig. 3 represents a plan view of the machine. Fig. 4 represents a front elevation. Fig. 5 representsa plan View of the box containing the coiling and feeding devices, with the cover removed. Fig. 6 represents a plan of the top of said box, showing the sliver-twisting device. Figs. 7 and 8 represent respectively vertical and horizontal elevations of the character of can which is filled by this machine.

The same reference characters indicate the same parts in all the figures.

In the drawings, 1 represents a main standard or supporting column, at the footof which is a base 2 which carries a rotating can support 3. At the top of the column is formed a table 4 on which is held rotatably a head 5 carrying a coiling and feeding box 6 and a lateral'extension 7. In the box 6 is contained a pair of feed rolls or calender rolls 8 9 and a coiler 10.

Above the box is a twisting device 11 for twisting the fibers in the sliver 12, which passes through the twisting device and is delivered from one end thereof so as to pass Ithrough an orifice 13 in the cover 1410f the The rotary support 3 is adapted to hold a. suitable receptacle for the fibrous material, such as the can 15, which has an outer perforated cylindrical wall '16 and an inner tubular perforated wall 17 concentric with the outer wall. Between the walls is'an annular space 18 in which the sliver of fibers is deposited in a series of loops, as shown in Fig. 8. The rotation of the coiler 10 forms the loops or coils, while the rotation of the can causes the coils to be deposited side by side in a circular series.

The sliver,.twisting, feeding and coiling devices, and the can support arealldriven by a vertical shaft 19 which receives motion through the bevel gears 20 and 21 and spur gear train 22 23 24 and 25,: the latter being moved by anysuitable source'of power. A gear 26 at the lower end of shaft 19 acts upon an idler 27 which meshes withand drives a gear 28 secured to the rotating sup! port. At the top of shaft 19 is a'bevel gear 29 which meshes with a bevel gear 30 on the shaft of the feed roll 8. On the same shaft is a pinion 31 which drives the other feed roll by acting upon a pinion 32 secured to the latter. The twister l1 isalso rotated by the same means as that which turns the feed rolls, for on the shaft of the roll 8 is a gear 33 meshing with a gear 34 fixed to the twister. In order that the sliver may be delivered centrally to the coiler, the feed rolls are arranged so that their line of tangency crosses the axis of the coiler and the delivery of the twister is in line with the same axis. This necessitates that the twister be angularly arranged with respect to the feed rolls in order that it may deliver directly above the nip of the rolls, and at the same time be rotated by the gear on the shaft of one of them. To permit driving on this angle the teeth of the gears 33 and 34 are inclined.

As before stated, the head 5 is rotatable upon the top of the column 1, its axis of rotation being that of the shaft 19 so that swinging of the head need not cause the gearing for the feeding and coiling mechanism to become disengaged. The head is held in place by brackets 35 secured thereto and carrying pins 36 which are furnished with rolls 37 bearing on the under side of the table 4, and it has sufficient amplitude of swing to bring either the coiling and feeding devices or the extension 7 over the support and the can placed thereon.

The extension 7 supports guides 38 through which pass vertical rods 39 connected to an annular plate 40 which is adapted to enter the space 18 of the can and compress the fiber therein. Above the guides 33 the rods 39 are connected by a cross piece 41 from which rises a tongue 42 having a plurality of holes 43 for the insertion of a pin 44 to pivotally attach an operating lever 45 thereto. The rods 39 are constrained by the guides to travel in rectilinear vertical paths, and consequently the pivot pin 44 moves in such a path. To permit such movement the fulcrum 46 is carried by an arm or link 47 pivoted to the head at 48 so that it may shift as shown respectively in full and dotted lines in Fig. 2. It is to be noted that the rods 39 and cross bar 41 are all in one plane with the link 47 and pivots of the latter. Consequently whatever lateral thrust may be applied to the rods when the lever is above or below its horizontal position is applied in this plane and therefore is resisted by the combined stiffness of the rods and cross bar. In the construction where the rods of the packer are in a plane transverse to the lever there is less resistance to bending, for the only force to oppose the transverse pressure of the lever is the stiffness of each separate rod. In the construction here shown, however, the two rods 39 and cross bar 41 together form a frame of much greater stiffness so that there is less danger of the rods becoming bent.

Stops 49 and 50 are provided on the table 4, of which the former by cooperation with the bracket 35, shown at the right hand of the column in Fig. 1, arrests the head when the coiling device is directly over the can support, while the second top is struck by the bracket 35 at the left of the column and arrests the head when the packer is above the support. The coiling and feeding box remains above the can until the latter is completely filled with loose fiber, when the head is shifted to bring the packer over the can and the latter is depressed until the fibers are sutlieiently packed together. They are retained in this condition by the 111621115 described in my application Serial No. 315,453, above referred to, while the head is swung to bring the coiling box again above the can. The ren'iaining space is filled as before and the newly-admitted fiber compressed in the same way. These steps continue alternately until the can is full and the fiber is all packed together with exactly the right amount of space between the fibers.

It will be olservcd that the oscillating movements of the head can be made with much greater rapidity than the can can be displaced from the rotating platforn'i and moved back and forth from the feeder to the packer, and that the lever for operating the packer is always in place. Accordingly the cans can be filled most rapidly by the use of the machine hereinbefore described.

I claim 1. A machine for coiling and packing fiber, including a support adapted to hold a. receptacle, a head mounted above said support, coiling and feeding mechanism carried by said head, and a presser also carried by said head, the head being laterally movable to place the ceiling and feeding mechanism and the presser alternately over said support and over a receptacle thereon.
